ISO 6806:2017 specifies the minimum requirements for rubber hoses and hose assemblies for use in oil burners.The following two types of hose assembly are specified.- Type 1: Hose assemblies for flux and reflux, but not for insertion between the oil burner pump and the atomizing connection; maximum working pressure 1,0 MPa (10 bar); maximum oil temperature 100 °C.- Type 2: Hose assemblies for insertion between the oil burner pump and the atomizing connection; maximum working pressure 4,0 MPa (40 bar); maximum oil temperature 100 °C.The hose assemblies specified in this document are not intended to be used, without special assessment, for purposes other than oil burner installations.
